This invention relates to'improvements in hydro extractors for thetreatment of textile fabrics.

In the following specification and claims the term hydro-extractor isintended to cover not only apparatus for and the removal of 'water butalso for the removal of other liquids and similarly the termhydro-extractions is intended to cover the removal of Water and otherliquids.

The bleaching, dyeing and finishing of textiles usually takes place inwater or other liquid medium and after most of the operations connectedwith these processes the liquid has to be removed therefrom. This isdone as far as possible by mechanical means and the remaining liquid isremoved by evaporation in drying machines which use heat. Suchmechanical drying means include hydro-extraction and mangle's.Mechanical drying by hydro-extraction may be carried out in various Wayse. g. by centrifugal hydro extraction, which is eificient but does notwork continuously and may damage delicate fabrics and by suctionhydro-extraction which hitherto has only been used for goods in fullwidth and can therefore not be used for continuous processes, where thegoods are treated in rope form. In many continuous processes fabrics aretreated in rope form and if the liquid has to be removed between eachprocess only the mangle is available which as stated is unsuitable fordelicate fabrics.

'I'he object of the present invention is a device which will permit thecontinuous suction hydroextraction of fabric in rope form withoutdamaging the fabric, which can be applied under most conditions, fittedto existing machines or used as a separate unit.

The suction hydro-extraction device according to the invention consistsof a short length of round, oval or other shaped tube provided with oneor more apertures, slots or series of perforations at one or more areasof its surface the aperture or apertures or slots or perforations beingconnected to a vacuum pump or other source of suction preferably througha water separator.

The invention is illustrated diagrammatically in and will be describedwith reference to the accompanying drawings which show severalembodiments of the invention. In these drawings:

Fig. 1 is an elevation of a simple form of the invention, including thesuction producing means;

Figs. 2 and 3 are a sectional elevation and sectional plan respectivelyof a form of the invention wherein the tube is formed with a singleslot, the area of the tube where the slot is located being surrounded bya jacket;

3 Claims. (01. -306) Figs. 4 and'5 are an elevation and a sectional planrespectively of a form of the invention wherein the tube is formed witha plurality of perforations, the area of the tube where the perforationsare located being surrounded by a jacket;

Fig. 6 is a perspective sectional view of a form of theinvention'similar to that shown in Figs. 4 and 5 showing a fabric inrope form being drawn through the device by a roller.

In all the forms of the invention A is the tube through which the fabricis passed in rope form and B is the suction pipe which is connected to asuction or vacuum pump H by a pipe h, the pump exhausting through thepipe 71, as shown in Fig. 1.

Fig. 1 shows the simplest form of the invention in which a singleaperture (1 is" formed in the bottom portion of the tube A and isenclosed by a jacket C which communicates with the aperture, and thesuction pipe B is connected to the jacket 0 on the tube A.

Figs. 2 and 3 are detail .views of the tube A formed, as shown in Fig.1, with a single slot (1 in the bottom portion of the tube, the area ofthe tube in which the slot is formed being enclosed by the airtightjacket 0 to which the suction pipe B is connected. Instead of a singleslot a as shown in Figs. 1, 2 and 3, two or more apertures or slots maybe formed in the bottom portion of the tube A all the slots beingenclosed by a single jacket.

Figs. 4 and 5 show the tube A formed with a plurality of perforations ain the lower portion, the area of the tube in which the perforations arelocated being surrounded by the air tight jacket C to which the suctiontube B is connected.

In the previously described forms of the invention the aperture or slotoi or perforations a are formed in the lower portion of the tube A and asingle suction pipe B is connected to the lower part of the jacket Csurrounding it.

The operation of the device is illustrated by Fig. 6 which shows alength of fabric D in rope form being drawn through the tube A by the.

driven roller E, whilst suction is continuously applied to the pipe B,which causes air to enter each end of the tube A.

Although in the various figures of the drawings the tube A is indicatedas being circular in cross section it may be of oval or any othersuitable shape for the passage of the fabric in rope form, and it maymade of any suitable material such as metal, glass or synthetic glass orsyntheticresin.

The device comprising the tube A and suction pipe B and the suction orvacuum pump con- 3 nected to the pipe B may be carried on a moveableplatform to constitute a self contained unit or the pump may be separatefrom the device and suitably connected thereto in which case a singlepump can serve a number of tubes.

By using a suitable suction or vacuum pump the device will hydro-extractthe fabric passing through it to the same extent as a full width suctionhydro-extractor.

I claim:

1. A suction hydro-extractor for the treatment of textile fabricscomprising a tube open at each end for the passage of the fabric in ropeform and entrance of air, an air tight jacket enclosing a portion of theperiphery of said tube, the jacket being in communication with theinterior of the tube, a suction pipe connected to the interior of theair tight jacket, and suction producing means connected to said suctionpipe.

2. A suction hydro-extractor for the treatment of textile fabricscomprising a tube open at each end for the passage of the fabric in ropeform and entrance of air, an air tight jacket enclosing a portion of theperiphery of said tube, the jacket being in communication with theinterior of the tube through an aperture in the wall of the tube, asuction pipe connected to the interior of the air tight jacket, and.suction producing means connected to said suction pipe.

3. A suction hydro-extractor for the treat- 4 ment of textile fabricscomprising a tube open at each end for the passage of the fabric in ropeform and entrance of air, an air tight jacket enclosing a portion of theperiphery of said tube, the jacket being in communication with theinterior of the tube, a suction pipe connected to the interior of theair tight jacket, suction producing means connected to said suctionpipe, and means for drawing the fabric through the tube.
